Progression

Originally posted on r/Fitness by user nSuns. Five days, alternating heavy and volume waves, with the program's progression keyed to how your AMRAP sets go.

It suits intermediates who can recover from five sessions a week and want fast linear-style gains for 8-16 weeks.

Know this before you start, because nSuns leans on it hard: RepRoute does not manage the AMRAP-driven progression for you. The progression math never reads the set type, so it cannot see that a set was an AMRAP or how many reps you hit on it. RepRoute ships the structure and logs your work — you apply nSuns' progression rules yourself.

Pros

  • Very high volume → strong hypertrophy response
  • Rapid strength gains for intermediate lifters
  • Built-in weekly progression

Trade-offs

  • 6 days/week is demanding on recovery
  • Not suitable for beginners
  • High injury risk if sleep/nutrition aren't solid

RepRoute adaptations

  • Ships the nSuns structure as authored — five days, heavy and volume waves
  • Equipment substitution when a lift needs kit you don't own
  • Injury flags remove the conflicting movement patterns from your plan
  • PR detection on logged sets, plus a deload banner when your recent training warrants one

Common questions

No. The progression math doesn't read set types at all — an AMRAP set is logged like any other. nSuns' rep-based progression rules are yours to apply.

Most lifters run it for 8-16 weeks before recovery limits force a change. RepRoute won't nudge you to switch — there's no program-transition recommender in the app.

No. Stick with GZCLP or StrongLifts until linear progression stalls, then consider nSuns.
